TO ALL WHOM IT MAY CONGERN:

, lie it known that I, Fxrinnn PowsR, of St. Louis, in the county of St. Louis, and State. of Missouri, have made certain new and useful Improvements in Kiln's; 'and-I do hereby declare that the following is a full and clear description thereof, reference being hud to the accompanying drawings, and to the'lettersmf reference marked thereon; l i I 4 The object of this invention is to construct a kiln'for burning bricks, vstone-wore, and such other like-articles, in a much cheaper and more expeditious manner .than it can now be accomplished.

The invention consists in constructing a. series uf log, narrow chambers, etched over the top vwith brick,

vvalls, andoorcd with iron plates,A beneath which are'subterranean smoke-passages in all but one compartment, which is to be used es the kiln proper, while the'4 others are 'only drying-chambers. The iiresaretto be built under the kiln proper, from whence the smoke and hot gases escape under the-.ironloors of the dryinggchambers, and pass thence up a smoke-flue built outside of them. 'In passing under the aforesaid iron tloors,the hot'gaseh 'und smoke impart to the drying-chambers `such adegree of hes'tas to thoroughly dry and warm the green bricks or vwere preparatory to-their entering the highly-heated kiln-.l 4.lh'e bricks or other articles to be burned ereto he placedbn cars or platforms, und passed successively through the whole series of chambers, commencing vin the coolest andfinishing inthe hottest or kiln proper. The invention also relates to various other devices, r'vhich will be hereinafter more fully explained, l

To enable those skilled' in the lnrt to mzke und use my improved kiln, I will proceedto descibe'its construction and operation.A

' `Figure 1, of the drawings, isfa general plan of the kilnnnd drying-chumhers.

Figure 2 is a lcentral sectional elevation of-theseme. l The kiln A isA enclosed by the walls a o n its two sides and top, both ends being left open. The dryingchmnbersv A1 A A are built in s. similar manner, as relates to the side and top wells a. The kilnA is enclosed hy double walls, so as to leave an air-chamber, al., between them. An orifice, or series of orifices, a, in the front of the kiln, permits the external air to enter into the ehe'mber l(t1, andecurrentis thereby crested inthedirec` tion of the arrows z, the-said current becoming heated in the chamber a" to e. very high degree, and it is passed thence through apertures a.s into the drying-chuinber Al, thence through the apertures' sfinto vthe next ycheni-l ber, thence through the apertures a injtothe chamber A3,'nnd .thence through the aperture a.6 into the chimney B. In this mannerthe heat'geuerat'ed around the kilnis utilized in drying the bricksor other articles gin-the drying-chambers. Y i h The fires are to be built on the grate-bars C, through' the doors c, und Vthersrnoke'nnd hot gases will pass through one ormore lues, c, into the' s ubterraneous passages Cbene a.th the4 irox'i'A iloors E, that form the bottoms of the drying-chambers, and so on, throughthenperture cz, in to the base of the smokestack.

`It is evident, from the foregoing description, that o. large amount of heat will be imparted tothe plates'E, landfrom them to the drying-chambers above,- vwhich heut muy very readilybe'employed in d rym'g und hetxng the bricks, or other articles to be hurncd,'before they enter'the kiln proper'. y

The bricks, or otherarticles to be burned in this kiln, are to beplaced ou platforms, (n ot showin) and shoved into the kiln ordryngchambeI-A, iirst in the direction of the arrow y. As soon as this lchamber shall have beco'tne filled iu this manner, the foremost platform will-be -drnwn out on the turn-table F, which will then be turned around so us to placethe loaded platform before, and in position to enter the chamber A, which chambex- `vill than be" lled with the loaded platforms as they come'fnom A3. When A is-illed in this mannexgthe plstforms willin succession be. placed onthe turn-teble F5., and turned nr'oun'd `and sent into the'chamber A?, then on the turn-table'Fi,` and turned into the kilo. A, where thebrieks or other articles will be thoroughly burned und finished. l I

Thus itpwill'be seen this apparatus is acontinuous .kiln and dry-house, eminentlyadaptedto drying' and burning bricks or pottery-Ware..V The heat in the remote chamber Alwill be so mild as not t'o xnJure-or crack the greenarticles placed therein, and the temperature is so graduslly raised in the successive chambers A A1 as tolmperceptibly heat the articles placed therein, und prepare them, Valmost red hot-,to enter the highly-heated kiln'A, where they may be readily finished in a very short time, and more thoroughly und evenly than they could be in those kilns where the articles are piled in in large masses.

n passing through tho various chambers of this kiln and dry-houses, the platforms, on which the bricks, kc., are placed, slide in on stationary rollers, whichmay be placed entirely across the chnmber, as those marked Gr,l or they muy'be simply short rollers` or sheaves, as at G in the furnace-compartment. The short rollers would probably be'less liable to heat and bend than the long ones. In either case, shelf, g, will be madein the brick-work, for sustaining the rollers, be'ring rods g.

The turn-tables F F1 l?2 are simple frames,f, carrying rollers, fl. The frames are pivoted on one-side atf, und on the other side sustained on two whcels,f3, which run on the curved trzlckf, the whole arrangement being such as to allmvthe tnble to turnaround from one chamber to another.

Of course the number of drying-ehambers may be increased ndeinitely, buttl1ree will prob/ably be found to bc usually suicient. l I

The-fonndations ot' the-walls, and the smoke-,passage C, should be sunk'intc thegroundfar encughto bring the doors on a. level with thesnrfnce, or but slightly raisodabove it,

l In order to economize the` heat generated in the kiln to ns great :in extent es possible, the walls of the kiln proper-nre to be built high enough to allow a chamber for the steam-boiler H (which is to genera-to the .steam for driving the works) above the place occupied by the burning bricks, 13m.

` Having described my invention, what I claim, isl 1.- The kilnA A, and drying-chambers A1 A2 A3, when combined and arranged ns herein shown lnd described` 2. The turn-.tables F I"1 F, when combined vwith-the drying-chambers and kiln, as described sndset forth FIELDER POWER.
